django - 类型错误 : __init__() got an unexpected keyword argument 'widget'

Question

我在运行命令python manage.py runserver时遇到运行时服务器错误。终端显示错误:第 35 行，在 CustomertaskForm,startdate=forms.DateInput(widget=forms.DateField()) TypeError: init() 获得意外的关键字参数 'widget'

表单.py

class CustomertaskForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
        super(CustomertaskForm, self).__init__(*args, **kwargs)

    title=forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'required': 'required'}))
    discription=forms.CharField(widget=forms.TextInput(attrs={'class': 'form-control', 'required': 'required'}))
    startdate=forms.DateInput(widget=forms.DateField())
    enddate=forms.DateInput(widget=forms.DateField())

    class Meta:
        model=Customertask
        fields=['title','discription','startdate','enddate']

模型.py

class Customertask(models.Model):
   title=models.CharField(max_length=200)
   discription=models.CharField(max_length=500)
   startdate=models.DateTimeField()
   enddate=models.DateTimeField()

查看.py

def createtasks(request):
if request.method == 'POST':
    form=CustomertaskForm(request.POST)
    if form.is_valid():
        tasksave=Customertask.objects.create(
            customer=models.ForeignKey(Customer)
            title=form.cleaned_data['title'],
            discription = form.cleaned_data['discription'],
            startdate=form.cleaned_data['startdate'],
            enddate=form.cleaned_data['enddate']
        )
        tasksave.save()
        return HttpResponseRedirect('/customer/tasktable')
else:
    form=CustomertaskForm()
return render(request, 'customer/createtasks.html', {'form': form})

迁移是否重要，每次 models.py 或 forms.py 发生变化时......请对迁移给出明确的评论。

Answer 1

您的小部件和字段的方式是错误的 - DateField 是一个字段，DateInput 是一个小部件。因此，您的表单使用 forms.DateField(widget=forms.DateInput())。但是，由于 DateField 默认情况下使用 DateInput，因此您可以完全删除小部件参数:

class CustomertaskForm(forms.ModelForm):
    ...
    startdate=forms.DateField()
    enddate=forms.DateField()

顺便说一句，您可以通过保存模型表单来创建任务。您不需要手动调用 Customertask.objects.create():

if form.is_valid():
    tasksave=form.save()
    return HttpResponseRedirect('/customer/tasktable')
